Level 3 BLAS
Most of the Level 3 BLAS is derived from GEMM, so that is the primary focus of the optimization.

Famous quotes containing the word level:
“Adults understandably assume that the level of verbal proficiency a five-year-old displays represents his level of proficiency in all areas of functioning—if he talks like an adult, he must think and feel like one. However, five-year-olds,... belie the promise of adult-like behavior with their child-like, impulsive actions.”
—Dorothy H. Cohen (20th century)
